Oro eggs can be found in pots of gold at the end of rainbows. At least, that's what leprechauns tell everybody. (They're known for playing tricks!)
Many say that the Oro's existence is a counterbalance to the attitudes and ideals of the Dragolds. The Oro is the exact opposite of the Dragold—whereas Dragolds hoard their material possessions, Oros collect treasured items only to turn around and give them away. Some say that Oros even give their possessions away to those who are greedy and that the greedy person is transformed into a generous person upon receiving the gift.
